S.934 and H.4575 would each require the board of trustees of each school district to prohibit students from using “wireless communication devices” (cell phones) during school hours. There may be legitimate uses for cell phones during school hours that a blanket prohibition would impeded. For example a student may forget to bring a calculator and may wish to use a calculator app on their phone as a substitute. In any case this is a matter best left to the discretion of the administrators of each school district or school rather than the state legislature.
